Using the law of cosin
cos(angle) = adjacent leg / hypotenuse
We fill in what we know and solve for x:
cos(30) = x / 10
x = cos(30) * 10
x = 5 SQRT(3)
Answer:
260?
Step-by-step explanation:
I used the equation (4)13+(16)13 and plugged it into my calculator and got 260.
No, you can't do it using integers. But the question doesn't restrict you to integers anywhere. It simply asks what 'x' produces the same output from both machines.
The upper machine produces x^2+2.
The lower machine produces (x+2)^2.
If the outputs are the same, then
x^2+2 = (x+2)^2 .
Crunch THAT through your own solve-o-matic machine, and you find that it works when x= -1/2 .
Answer:
7y = x + 28
Step-by-step explanation:
Given x = 7t and y = t + 4
Here t is the parameter Now to remove it express one of it in terms of the variables (like x or y)
Given x = 7t
from this we can write
Now substitute this value in the second equation
y = t + 4
Therefore the parameter is eliminated.
Answer:
A. A boxplot of the data has multiple large outliers.
D. A boxplot of the data shows a very slight skew.
Step-by-step explanation:
A) The normal distribution does not have outliers. The outliers are any point outside the 3σ interval which 99.7% of the data. The 0.3% data would not be outliers.
B) YEs the mean and median of the normal distribution are nearly equal. AS it is asymmetrical.
C) When the sample standard deviation is large the data is spread about the mean. The normal distribution is flatter and wider
D) The normal distribution is never skewed.If one end is longer then the distribution is not assymmetric and the normal distribution asymmetric meaning half is the mirror reflection of the other half.
So A and D indicate circumstances where he not be safe to use a t procedure.
